## Determine paper weight with weight table or paper weight calculator

Whether business cards, brochures or flyers - the weight of the paper has a decisive influence on the appearance of the print as well as on the costs of the associated mailings. But which grammage is suitable for which purpose? And what is a grammage anyway? We have compiled the most important facts about paper for you.

## Definition of paper weight

The paper weight (also called *grammage* ) describes the weight per unit area of paper and other printable materials such as textiles. The sizes are specified in the unit **gram per square meter (g/m²)**. From wafer-thin tissue paper (25 g/m²) to sturdy cardboard (600 g/m²), this fascinating medium offers a wide range of options for putting the finishing touches to your advertising campaign.

### How is the paper weight calculated?

The exact grammage of paper is determined using the sheet size in cm and the paper weight in g/m². These two values are multiplied and then divided by 10,000.

So how much does a standard DIN A4 sheet weigh? According to the formula, classic copy paper **with 80 g/m²** is (29.7 x 21) x 80 g/m² divided by 10,000, i.e. **4.99 g per sheet**.

#### Calculation formula sheet weight

The weight of a sheet of paper (Bg) can be determined with a simple multiplication:

Length

(l) in cmx width (b) in cmx basis weight(fG)/ 10,000 = sheet weight(Bg)Example calculation: How heavy is an A3 sheet of 135 gram paper?

42 x 29.7 x 135 / 10,000 = 16.839 grams

Here's an important note. Since paper is a natural product,production-related deviations of 5 to 10% from the specified grammage are possible.Use our

### Which paper weight should you choose for which products?

Brochures, posters, postcards, letterheads - they all serve the purpose of advertising and are used in a wide variety of places.

The classic paper is *the* **copy paper**, which is used in most home printers or office equipment. The paper weight here is **80 g/m²**. However, this weight is only suitable for one-sided printing - for **duplex printing**, a paper weight of **90 g/m²** is recommended, as it has a higher opacity value and is therefore less transparent.

To create **DIN long standard flyers** (six-sided), it is best to choose a matt image print on **135 g/m²** paper. A glossy print is visually appealing, but less legible due to the reflection. **Postcards** are printed on **235 - 350 g/m²** paper as standard, as they are usually sent without a protective envelope. **Business cards** should be even more stable - their standard weight is **250 to 450 g/m²**.

### What is the grammage?

The grammage is the weight specification for paper. It is always given in grams per square metre. Newspaper, for example, has a weight of 50 grams per square metre (abbreviated to g/m² or g/sqm), copying paper 80 g/m² and a postcard 180 g/m². The decisive factor for the paper weight is always the thickness of the paper. The following applies: Thinner paper (newspaper) is lighter than thicker paper (postcard).

The grammage of a paper can be calculated exactly according to a certain formula. The weight of the paper format is first multiplied by a factor of 10,000. The product of this multiplication is then divided by the product of the length and width of the paper format. The term paper size always refers to a specific piece of paper, such as a sheet of copy paper.

Grammage specifications play a particularly important role in direct marketing. Here it is not least important to keep an eye on the costs. In a mailing campaign, these are decisively determined by the postage. The postage costs, in turn, are essentially dependent on the weight of the letter. Since a single piece of paper is rarely placed in the envelope for a mailing, but often folders or brochures, the paper naturally plays a major role in the total weight of a mailing. Relatively thin paper is an important contribution to keeping the costs of mailing as low as possible.

### What role does paper weight play in a mailing?

Especially in direct marketing, the paper weight has a decisive influence on the cost of mailing. Here it is important to consider all factors such as exact paper weight and the weight of the envelope.

When it comes down to it, when calculating the cost of a printed matter, it should be taken into account that printing ink, any finishing foils or staples also weigh something.

Mailing is still one of the most efficient methods in direct marketing. With this form of advertising, you should pay particular attention to the weight of the paper, because it determines how high your costs are for the postage incurred. Here is a small example: You print a mailing which contains a letter with 3 sheets. You use paper with a weight of 90 g/m², which is somewhat more tear-resistant than the standard paper with 80 g/m². The letter will be heavier than 20 grams and will cost you 0,35 Euro instead of 0,28 Euro mailing postage per unit.

Please do not forget to include the weight of the envelope when calculating the mailing costs. A standard DIN-long envelope weighs about 4.5 grams. In addition, about 5 to 10 percent of the paper weight is added for the printer ink.
